The beginning of a new year is the perfect time to upgrade your self-care routine. If one of your 2022 wellness resolutions is to revitalize your hair, we have some good news for you. The salon-quality Redken Extreme Length Shampoo and Conditioner Set (Buy It, $30, was $46, amazon.com) that gives shoppers "longer and thicker" hair is on sale for $30 at Amazon. 

Both the shampoo and conditioner are made with biotin as their main ingredient. According to board-certified dermatologist Dr. Debra Jaliman, "Biotin helps nourish the hair follicles and stimulate the growth of existing hair." She also said that the vitamin helps increase the production of keratin, which she explained as "the protein that strengthens hair." So, not only do these hair care products encourage new growth, but they also prevent damage to your existing locks. 

In the reviews section, more than 1,300 Amazon shoppers have given these products a five-star rating. "I just finished my first bottle of both shampoo and conditioner," one began. "I'm impressed. My hair always breaks at my collar in the back, but this stuff has it finally growing back there. But that's not the best part, I have new hair growth all along my hairline. It's amazing. I'm a believer. I have fine, thin, wavy/curly hair, and it's never looked better." (Related: This $8 Leave-In Conditioner Is 'Liquid Magic' for Fine, Thinning, and Damaged Hair)

Other shoppers were amazed at how quickly they saw results after switching to these products. "I had the dead ends cut, started using this product immediately, and four weeks later, it had grown almost 2 inches. I am very happy with the results," a second reviewer said.

A third buyer added that their hairstylist recommended using the Redken Extreme Length line. "He said my hair had a protein deficit, which explained the dry, damaged–looking hair," the shopper said. "This is an outstanding product. My hair is now smooth and shiny."

This year is all about putting yourself first, and you shouldn't have to settle for anything less than soft, healthy hair. Treat yourself to the Redken Extreme Length Shampoo and Conditioner Set while it's on sale for $30 at Amazon.
